Compare any two graphics cards:
GeForce RTX 2070 Super vs GeForce RTX 2080
IntroThe GeForce RTX 2070 Super has core speeds of 1605 MHz on the GPU, and 14000 MHz on the 8192 MB of GDDR6 RAM. It features 2560 SPUs as well as 160 Texture Address Units and 64 Rasterization Operator Units.
Compare that to the GeForce RTX 2080, which has core clock speeds of 1515 MHz on the GPU, and 14 MHz on the 8192 MB of GDDR6 memory. It features 2944 SPUs along with 184 TAUs and 64 Rasterization Operator Units.
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
Both cards have exactly the same memory bandwidth, so theoretically they should perform the same. (explain)
Texel RateThe GeForce RTX 2080 is a bit (more or less 9%) better at AF than the GeForce RTX 2070 Super. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce RTX 2070 Super is a better choice, but not by far. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
